DETAILED DESCRIPTION OF THE INVENTION

Referring now to the drawings, and more particularly to FIG. 1, there isshown a collar assembly 10 including a collar strap 12 and a trainingmodule 14. Collar strap 12 is arranged to be placed about the neck of ananimal and adjusted to appropriately snug training module 14 against aportion of the neck of the animal.

Now, additionally referring to FIG. 2, training module 14 includes ahousing 16, an electrode probe 18, an electrode probe 20, a batterycontact 22, a signal emitter 24 and a programmable device 26. Housing 16is connected to collar strap 12 and encloses programmable device 26completely. Housing 16 is hermetically sealed. Additionally housing 16may be molded to completely encapsulate all of the components therein.Extending from housing 16 are electrode probes 18 and 20, which delivera stimulus to the animal at appropriate times, as determined byprogrammable device 26. Housing 16 includes a removable and/orrechargeable battery, not shown and housing 16 specifically has abattery contact 22, which for the sake of clarity is illustrated as asingle battery contact 22 without illustrating an associated batterycontact.

Signal emitter 24 may be a light emitting diode (LED) 24 or an acousticdevice 24 such as an audio speaker 24 or a piezoelectric sound emitter24. Signal emitter 24 is operatively powered by a battery, not shown,and is connected to programmable device 26 for the conveying ofinformation from programmable device 26 by way of signal emitter 24.Information conveyed by way of LED 24, during normal operations ofcollar assembly 10, may include operational status of training module14, condition of the battery and/or acknowledgment of the receipt of amessage from a transceiver, not shown. Acoustic device 24 may be used toemit acoustic signals as instructions or warnings to the animal.

For the sake of clarity, other elements which may be included intraining module 14 have been omitted, such as a radio transmitter and/orreceiver and separate memory, which may be a part of programmable device26. Programmable device 26 is operatively connected to signal emitter 24and electrodes 18 and 20. The connection is simply shown as a line inthe schematic rendering of FIG. 2 and it should be understood that aseparate high voltage circuit is connected to electrode probe 18 and/or20 during operational use of training module 14 and that the connectiondirectly shown with programmable device 26 may be disconnected duringthe operational use of training module 14.

As mentioned earlier housing 16 may be a completely sealed unit, whichdoes not lend itself to replacement of memory devices therein. Theconstruct of a sealed or molded housing 16 would result in a destructivedisassembly of housing 16 in the event access to components withinhousing 16 is desired. The advantage of having a sealed and/or moldedhousing 16 is that training module 14 is then highly impervious tomoisture and may be simpler to manufacture. It may become necessaryafter training module 14 has been manufactured to modify the functionand/or performance characteristics thereof. An advantage of the presentinvention is that it allows the product to be reprogrammed following themanufacture when normal microprocessor programming inputs are no longeravailable.

A programming apparatus 30 is interconnected with training module 14, asshown in FIG. 2. Programming apparatus 30 includes a signal detector 32that is connected by way of conductor 34. Signal detector 32 ispositioned proximate to signal emitter 24 to allow information to becommunicated from programmable device 26 to programming apparatus 30.Signal detector 32 may be a light detector 32 if signal emitter 24 isLED 24, and signal detector 32 is a microphone 32 if signal emitter 24is an acoustic device 24. Conductor 36 connects programming apparatus 30to battery contact 22. Conductor 38 connects programming device 30 tofirst electrode probe 18. Conductor 40 connects programming apparatus 30to second electrode probe 20. Programming apparatus 30 receivesinformation by way of signal emitter 24 as signal emitter 24 is pulsedand/or modulated by programmable device 26. Information is sent toprogrammable device 26 by way of conductor 38, which is communicativelyconnected to high voltage electrode probe 18. Conductors 36 and 40 areutilized by programming apparatus 30 to place programmable device 26into a mode that allows the reprogramming of programmable device 26. Forexample, a voltage level and/or current is passed between batterycontact 22 and electrode probe 20 to cause programmable device 26 toinitiate method 100, described later. Once programmable device 26 isplaced into a programming mode electrical signals on conductor 38 allowprogramming apparatus 30 to send information through high voltageelectrode probe 18 to programmable device 26. Information in the form ofacknowledgement signals or other information may be passed by way ofsignal emitter 24 through signal detector 32 by way of electricalsignals in conductor 34 to programming apparatus 30.

A desired program, to be placed into programmable device 26, iscontained within programming apparatus 30 and once programmable device26 is placed into a programmable mode, programming apparatus 30 sendsthe new program. The information bytes of the new program are sent as anelectrical signal by way of high voltage electrode probe 18, which isthen received by programmable device 26. Programmable device 26 sendsacknowledgement signals that the information is being received by way ofsignal emitter 24 and the information is stored in a memory, which maybe a part of programmable device 26 or a separate memory, not shown.This allows the programming and reprogramming of programmable device 26by utilizing the available electrical, acoustic and/or opticalconnections to interface and communicate between programming apparatus30 and programmable device 26.

While training module 14 of collar assembly 10 is reprogrammed byutilizing battery contact 22 and high voltage electrode probe 18 toplace programmable device 26 in a programming mode, the use of thesecontacts are illustrative and other contacts may be used to accomplishthis function. Programmable device 26, which may be a microprocessor, isheld in a reset state when voltage is applied between battery contact 22and stimulation probe ground electrode 20. Training module 14 may bepowered by an internal rechargeable battery, if the replaceable batteryis removed.

Now, additionally referring to FIGS. 3A-3C, there is shown a method 100,which can represent an embodiment of a method carried out by programmingapparatus 30 and programmable device 26 for the programming ofprogrammable device 26. At step 102, programmable device 26 is placedinto a boot load mode by action of programming apparatus 30 by thesupplying of a voltage between battery contact 22 and electrode 20. Timeis checked at step 104 to determine whether a predetermined time haspassed and if not a check is undertaken at step 106 to see if a startbit has been received. If no start bit has been received method 100proceeds back to step 104. If the timeout at step 104 is exceeded thenmethod 100 goes to return 150 and training module 14 exits to the normaloperational mode and executes an operational program, not illustrated.If a start bit is received at step 106 then a message is obtained atstep 108. If the message indicates a start mode then the methodcontinues to step 112 and sends an acknowledge signal, which may be sentby way of signal emitter 24. If the message is not a start message thenthe method returns to step 104. In steps 114 through 120 there is acheck to see if too much time has expired and if so the method proceedsto step 122. If there is a start bit received at step 116 anothermessage is retrieved at step 118 until a predetermined message count isequaled at step 120. If the message count is achieved at step 120 method100 proceeds to determining if the message indicates a programming modeis to be started, at step 122. If the message is not that a programmingmode should be started then method 100 terminates by way of step 150. Ifa programming mode is initiated an acknowledge signal is sent at step124 and then a loop that includes steps 126 through 132 is initiated toobtain messages until a byte count is equal to a predetermined number,such as 5. If the message received is an erase command then the flashmemory segments of programmable device 26 are erased and anacknowledgement that the erase has occurred is sent at step 138. If themessage received is to write the data at step 140 then the data iswritten at step 142 and an acknowledgement is sent at step 144. Method100 then returns to step 126 to retrieve additional information. Oncethe information has been completed an ending message may be sent andmethod 100 ends and programming device 26 exits to the normaloperational mode. The mechanism for ending the programming mode is forthe removal of the reset signal from the device, which is a removal of avoltage level set between battery contact 22 and electrode probe 20.

Advantageously the present invention uses a methodology to update and/orreprogram microprocessor software in sealed electronic pet trainingproducts following the completion of normal manufacturing process andtests. This allows for changes and corrections to the performancecharacteristics of the product long after the product has beenmanufactured and is accomplished without any added cost of specialprogramming connection points, which would affect the appearance of theproduct. The internal microprocessor is programmed by utilizingavailable electrical connections and the optical indicator thatotherwise have other functions in the operational mode of the pettraining product. The method outlined as method 100 may be permanentlyprogrammed into the memory of programmable device 26, thereby allowingfor the initiation of method 100 when initiated by programming apparatus30.
